Lens

In photography and digital photography the lens is the part of the digital camera or video recorder that concentrates light and focuses the image. The lens itself is a single piece of glass (or other transparent materials) with one or more curved surfaces. Cameras usually contain a combination of lenses that receive light rays from an object and form an image on the focal plane.
